Transcatheter device for scoring calcifications and for cutting valve tissue

Abstract

A transcatheter device (10) includes a first jaw member (12), a second jaw member (14) and a linkage mechanism (16) coupled to the first and second jaw members (12, 14) for changing a distance between the first and second jaw members (12, 14). At least one of the first and second jaw members (12, 14) includes scoring structure (20) capable of scoring calcifications or tissue or any other anatomical structure, with a direction of a scoring force along a jaw closing axis (25) that extends between surfaces (22, 24) of the first and second jaw members (12, 14), respectively, which face each other. The first jaw member (12) has a cutting element (18) arranged to cut in a cutting direction (27) transverse to the jaw closing axis (25).
